Abstract (en)
This application discloses a battery unit (1000). The battery unit (1000) includes a housing (100), at least one cell (200), and a buffer (300), where the at least one cell (200) is accommodated in the housing (100), the buffer (300) is disposed corresponding to a side wall of the cell (100), the buffer (300) is provided with an accommodating cavity (305), a periphery of the accommodating cavity (305) includes at least one packaging structure (3010), the packaging structure (3010) includes at least one level of packaging region with a predetermined length, and when pressure in the accommodating cavity (305) exceeds packaging strength of the packaging structure (3010), the packaging region is opened to form a buffer space that communicates with the accommodating cavity (305), reducing influence caused by swelling of the cell.
